An emulgel-based delivery system formulated with sweet fennel essential oil was developed for the encapsulation of beta-carotene. Emulgels were stabilized by using a mixed emulsifier system consisting of fumed silica particles (Aerosil 200) and a green surfactant (Amidet-N). The influence of the microfluidization conditions on mean droplet sizes and the effect of the fumed silica concentration on the physical stability and rheological properties of emulgels were investigated. The emulgel that presented better physical stability was that formulated with 5 g/100 g fumed silica due to the role of Aerosil 200 as Pickering stabilizer and its enhanced rheological properties. The resulting beta-carotene-loaded emulgels successfully protected the encapsulated bioactive ingredient throughout the storage period.
